关于价夸克分布与海夸克分布的核效应

ABOUT THE NUCLEAR EFFECTS ON VALENCE QUARK DISTRIBUTIONS AND SEA QUARK DISTRIBUTIONS

提出了一个由轻子－核深度非弹性散射和核Ｄｒｅｌ－Ｙａｎ过程的实验数据得到价夸克分布和海夸克分布的核效应函数ＲΑυ（χｔ）和ＲＡｓ（χｔ）的方法。由这两个函数可以检验解释核效应的理论模型。以铁、钙。

A method is presented to get nuclear effect functions R A v(x t)and R A s(x t) on valence quark distributions and sea quark distributions from the data of 1 A DIS process,and nuclear Drell Yan process.Both the functions may be used to test the theoretical models explaining the nuclear effects.As a example,we have got of iron,calcium,and carbon nucleus by this method.
